(1) A manufacturer of tires believes that their mean time to failure (MTTF) is 20 613 km. They also believe that time to failure
ELEN [110]

Answer:

a) The probability of falling in the warranty period is 11.6%.

b) The warranty period need to be 19771 km to ensure that no more than 5 per cent of tires fail in the warranty period.

Step-by-step explanation:

a) To fall within the warranty period, the tire has to fail before the 20,000 km.

To calculate the probability, we first calculate the z-value:

z=\frac{X-\mu}{\sigma}=\frac{20000-20613}{512}=  \frac{-613}{512}= -1.197

Then, the probability of falling in the warranty period is:

P(X

b) To calculate this we have to go on from a P(z<z₁)=0.05. This happens for z=-1.645.

This corresponds to a value X of:

X=\mu+z*\sigma=20613+(-1.645)*512=20613-842=19771

The warranty period need to be 19771 km to ensure that no more than 5 per cent of tires fail in the warranty period.

7m + -10 =-10 what is m?
tigry1 [53]

Answer:

m = 0

Step-by-step explanation:

Given

7m + -10 = -10

Positive negative gives negative.

So the expression can be rewritten as

7m - 10 = -10

Add 10 to both sides of the equation

7m - 10 + 10 = -10 + 10

7m = 0

Divide both sides by 7

7m /7 = 0/7

m = 0
